Abstract：Grid-connected inverter is widely used in solar and wind energy generation. On the basis of the mathematical model of a single phase isolated grid-connected inverter, the resonance is decreased with passive damping, and current dual closed-loop control strategy with utility voltage feedforward is utilized. The influence of inhibiting resonance with different passive damping is analyed. The regulator parameters is designed with pole assignment method. The utility voltage feedforward principle to eliminate grid voltage disturbances was analyzed. Finally, the resistive load mutation simulation and experimental waveforms are presented. The simulation and experimental results proved that grid-connected current and grid voltage have the same frequency and phase.
